Wafer-scale silicon carbide meta-optic platform for robust multi-beam laser processing
Recently, the team of Professor Min Qiu at the School of Engineering, Westlake University, in collaboration with Dr. Kaikai Du's team at Moldnano(Hangzhou) Technology Co., Ltd, has developed a wafer-scale silicon carbide (SiC) meta-optic platform. By combining SiC diffractive optical elements (DOEs) with a metalens array, the platform separates beam splitting from individual beam focusing. The ...
MOREHigh-Brightness, Wide-Gamut, and High-Resolution Structural Colors via Ultrafast Laser Oxidation of Ti/TiO2 Films
Recently, a research team led by Professor Min Qiu at the School of Engineering of Westlake University has proposed a novel method for creating high-brightness, wide-gamut, high-resolution structural colors based on ultrafast laser-induced oxidation. This work, by constructing a Ti–TiO₂–Ti sandwich thin-film structure and employing picosecond laser to precisely control the oxidation process,...

MOREWinding coupling phase for pseudo-spin-derived topological photonics
Topology has brought novel physics perspectives and manipulation methods to optical research, with its hallmark achievement being the ability to enable unidirectional (reflectionless) and robust (highly tolerant to perturbations) transmission of light. Within this research domain, pseudo-spin-derived topological photonic crystals can achieve unidirectional, robust transmission of optical modes ...
